Hi Rick, That's interesting that Mini-Circuits used Parlyene. It's a very expensive material to use although a great solution to the problem. We have a Parlyene coating system at work and due to the

Hello Jon, How about a link to the site so we can figure out what you're describing? 73, -Gary K9GS GMDXA Web Site: www.gmdxa.org _______________________________________________ UR RST IS ... ... ..9
Hello Jorge, There is very little current flowing in each radial wire so the wire size matters very little. In your example you would be much better off with the 120 radials than 40. Keep in mind tho
The timing of this topic couldn't be better. I was doing some major rework on my 80M vertical this weekend. The old style radial system consisted of radials made from insulated wire with a chicken wi
Hello Guy and sorry for the very late reply, I should have given more detail on my, admittedly poor radial system. It is pretty sparse, consisting of only ~20 1/4 wavelength radials not very well dis

Is it OK to run the transmit and receive coax feed-lines together in the same conduit? Anything to watch out for? I suspect this could be a problem if there were common mode currents on either of the
There was also one of these at the University of Illinois that was decommissioned in the early 80s. I've seen this thing up close and there were even rumors of some of the W9YH club members hooking a
This is frustrating too from the US Midwest Herb. It happens all the time. Equally frustrating are stations in AF working EU & East Coast NA all evening and never standing by for Midwest stations. It
Thanks for the information Bernie. Believe me I'm not trying to kill the messenger or anything but this is precisely the problem with some Dx-peditions. At this time of year, in New York city, sunset

Here's how I lay radials in the woods with heavy brush. I have a ~15 foot long piece of wooden oak stairway handrail. The kind you see for basement stairs. It's about 2 inches in diameter and has a f
I think what you want is an un-un...not a balun. It doesn't sound like there are any balanced elements in your system. Perhaps something like this: http://www.balundesigns.com/servlet/the-Ununs/Categ
Tom is correct. It's probably unlikely that they're going to be on 160M at their sunset....they're going to be on other bands and their operating pattern, so far, has confirmed this. I would guess th
Very interesting and well done. Was it ever discovered what was actually causing the spurious signal? In other words, what did the station engineer do that caused the signal to disappear? Rudy is awe
Tonight PT0S was on 80M...big pile-up. Then went to 160 with a good signal. At the same time they were on 160 they also showed on 80M again. This time the 80M op was clearly not the same one as befor
Since I sort of started this with my post last night... I don't think that public humiliation is going to fix this problem. As others have pointed out, there is too much of a potential for abuse with
